DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical characteristics of the present invention will become apparent with the detailed description of the preferred embodiments accompanied with the illustration of related drawings as follows.

With reference to FIG. 1 for an exploded view of an electronic cigarette lighting device of the first preferred embodiment of the present invention, the electronic cigarette lighting device comprises a casing 10, a heat generating unit 20 and a slide cover 30, and the perspective view of the assembly is shown in FIG. 2.

With reference to FIGS. 1 to 3, the casing 10 is formed by engaging a bottom cover 11 with a top cover 12 disposed at a position opposite to the bottom cover 11, and the top cover 12 has a combustion-supporting hole 13 formed and reserved thereon.

The heat generating unit 20 is installed in the casing 10 and disposed at a position corresponding to the combustion-supporting hole 13. In an implementation, the heat generating unit 20 is mounted on a circuit board 21 and electrically coupled to the circuit board 21, and the circuit board 21 has a battery 22 electrically coupled to the circuit board 21 for supplying electric power required for the operation of the heat generating unit 20. In the figures, the circuit board 21 is electrically coupled to an electricity charging hole 14 of an external power supply, and the electricity charging hole 14 is exposed from the casing 10 to facilitate an access of power supply for charging the battery 22 and extending service life.

In addition, the circuit board 21 further has an electrical conduction area 23 and a status indicating light 24. When the electrical conduction area 23 is electrically conducted, the battery 22 supplies electric power for the operation of the heat generating unit 20 until the temperature reaches a combustion supporting temperature (or an ignition temperature for lighting a cigarette), and the status indicating light 24 is provided for indicating the using status or power level of the battery 22.

The slide cover 30 can be slidably installed on the casing 10 and normally covered onto the combustion-supporting hole 13 of the casing 10. In an implementation, the slide cover 30 has a through hole 31 formed on a surface of the slide cover 30 and alternately positioned with respect to the combustion-supporting hole 13. In addition, the invention further comprises a slide base 32 disposed in the casing 10, a spring 33 abutting the slide base 32, and an electrical conducting plate 34 alternately positioned with respect to the electrical conduction area 23.

When the slide cover 30 is pushed and slid, the slide base 32 is shifted synchronously to compress the spring 33, while the through hole 31 is shifted to a position aligned precisely with the combustion-supporting hole 13 of the casing 10, such that the heat generating unit 20 is passed through the through hole 31 and exposed from the combustion-supporting hole 13. In the meantime, the electrical conducting plate 34 is shifted to a position aligned precisely with the electrical conduction area 23 of the circuit board 21, so that the battery 22 can supply electric power for the operation of the heat generating unit 30 and let the heat generating unit 20 reach a combustion supporting temperature.

When a user releases the pushing force, the elastic force of the spring 33 abuts the slide base 32 to resume the slide cover 30 to its original position and cover the combustion-supporting hole 13. In the meantime, the electrical conducting plate 34 is also shifted to a position alternately arranged with respect to the electrical conduction area 23, so that the battery 22 no longer supplies electric power, and the heat generating unit 20 stops its operation.

With reference to FIGS. 1 and 4 to 6, the present invention is characterized in that a safety mechanism is installed between the casing 10 and the slide cover 30 for preventing an improper operation of the slide cover 30, so as to improve the safety of the electronic cigarette lighting device.

In the figures, the safety mechanism includes an elastic bracket 41 protruded from the top of the casing 10, a window 42 formed on the slide cover 30 and disposed at a position opposite to the elastic bracket 41, and a press button 43 with the bottom disposed at the top of the elastic bracket 41 and installed on the window 42. At the status when the slide cover 30 covers the combustion-supporting hole 13, a side edge of the elastic bracket 41 is protruded from the window 42, so that the slide cover 30 cannot be pushed or moved since the window 42 is blocked by the elastic bracket 41. When the press button 43 is pressed, the bottom of the press button 43 can press and shift the elastic bracket 41 downward, so that the side edge of the elastic bracket 41 is not longer protruded out from the window 42, and the is blocked status of the slide cover 30 can be released, and the slide cover 30 can be pushed and slid to expose the combustion-supporting hole 13.

When the user releases the press button 43 and stops applying the force of pushing the slide cover 30, the elastic force of the spring 33 abuts the slide base 32, so that the slide cover 30 resumes its original position to cover the combustion-supporting hole 13. In the meantime, when the slide cover 30 resumes its position to the window 42 disposed at the top of the elastic bracket 41, the side edge of the elastic bracket 41 is protruded upwardly from the window 42, so that the slide cover 30 cannot be pushed or slid since the window 42 is blocked by the elastic bracket 41 as shown in FIG. 4.

In other words, if the user wants to use the electronic cigarette lighting device, the user must press the press button 43 by a finger first to release the status of the window 42 from being blocked by the elastic bracket 41 for a normal use, so as to achieve the effects of preventing an improper operation of the slide cover 30 and improving safety. In addition, the user simply presses the press button 43 to release the safety mechanism. Therefore, the present invention provides a convenient operation while taking the improved safety into consideration.

With reference to FIGS. 4 to 6 for a preferred embodiment of the present invention, the slide cover 30 further includes at least one positioning column 421 extended downwardly from a side of the window 42, and the press button 43 has a pressing portion 431 with the top protruded upwardly from the window 42, and at least one positioning plate 432 extended towards the positioning column 421, and the positioning plate 432 has a positioning hole 433 formed thereon and disposed opposite to the positioning column 421 for embedding the positioning column 421, so that the press button 43 can be installed onto the window 42 easily.

In FIG. 4, when the pressing portion 431 is not pressed, the elastic bracket 41 props the bottom of the pressing portion 431 to maintain the window 42 to be blocked by the elastic bracket 41. When the pressing portion 431 is pressed to shift the elastic bracket 41 downward, the status of the window 42 from being blocked by the elastic bracket 41 can be released as shown in FIG. 5. Now, the user can apply a pushing force to the slide cover 30 to shift the slide cover 30 and expose the combustion-supporting hole 13 as shown in FIG. 6.
